My son just got into bow hunting and has had a couple shots at bucks the past two years. He hit them but did not get good penetration. We found blood but could not recover them . How many lbs. do you shoot with your bow and what speed is your arrow? I am trying to understand how he can get better penetration with his arrow's. He uses a rage 2 blade, but does not get good penetration. He pulls 50 lbs, so I don't know the answer how to help him. Any advice would be greatfull.........beautiful buck!!!!!!!
